4. Operating Instructions
Once the compressor is set up, you can begin inflating your tires. The 450P-A EF features an automatic shut-off for ease of use.
Tire Inflation Procedure:
- Connect to Tire Valve: Attach the inflation gun's chuck to the vehicle's tire valve stem. Ensure a secure connection to prevent air leaks.
- Turn On Compressor: Locate the power switch on the compressor unit and turn it to the 'ON' position.
- Begin Inflation: Press the trigger on the inflation gun to start the air flow. The compressor will begin to inflate the tire.
- Monitor Pressure: Continuously monitor the tire pressure using the gauge on the inflation gun.
- Automatic Shut-Off: The compressor will automatically shut off when the desired pressure is reached or when the trigger is released. This prevents over-inflation and reduces wear on the compressor.
- Disconnect: Once inflation is complete, release the trigger, turn off the compressor, and disconnect the inflation gun from the tire valve.
